CARBURETER.

Specification of Letters Patent.

Patented Sept. 6, 1921.

Application filed. July 5, 1919. Serial No. 308,845.

T 0 all whom it may, concern Be it known that I, SANDERS WALKER, a citizen of the United States, residing at Wichita Falls, in the county of WVichita and State of Texas, have invented certain new and useful Improvements in Carbureters, of which the following is a specification.

My invention relates to improvements in carburetors and in such connection it relates to that class of apparatus for carbureting air with the heavier liquid hydrocarbons, particularly crude oil.

The class of carbureters to which my invention relates is described and illustrated in Letters Patent No. 703,995, dated July 8, 1902, granted to Fred E. Caton and Franklin B. Warring, and consists in certain improvements which are in line with a carburetor of this description.

The principal object of my invention is to provide a carburetor of this type which shall be very simple in construction and operation.

In carrying out my invention, I provide a cylindrical casing inside of which a smaller cylinder is placed to act as a vaporizer, the exhaust from the engine being utilized to heat the small cylinder or vaporizer, onto which the crude oil is allowed to flow and is thus vaporized by the heat. Suitable means are also employed to regulate the admission of air to the casing and to provide for the outlet of carbureted air.

My invention will be more fully understood from the following description, taken in connection with the accompanying drawings forming part hereof in which- Figure 1 is a side elevational view of a carburetor embodying the main features of my invention.

Fig. 2 is a vertical sectional view.

Fig. 3 is a cross sectional view taken on line 3-3 of Fig. 2, and

Fig. 4 is a top view of one of the dampers.

Referring to the drawings, 1 represents the casing of the carbureter which has atop plate 2 bolted thereon and a bottom plate 3 with an opening to admit exhaust from the engine through a pipe 4 attached to the casing in any suitable manner. The

exhaust gases from the engine entering through pipe 4 are carried into the vaporizer which consists of a cylinder 5 attached to which is a neck 6. The exhaust gases from the engine passing up through pipe l heat the cylinder 5 and neck 6 constituting the vaporizer. The liquid to be vaporized, crude liquid hydrocarbon oil, for in stance, enters through a feed pipe 7 from a storage tank not shown and flows onto and around a collar 8 on the neck 6 of the vaporizer. This collar is constructed preferably of asbestos, although any suitable material may be used. The oil is thus carried around the collar and flows down the neck 6 and onto the cylinder 5 of the vaporizer, the heat causing the oil to vaporize. Sufficient gasolene is used to start the engine and as soon as the exhaust gases heat the vaporizer sufiiciently to vaporize the oil, such vapor is then used to carburet the air. The carbureted air passes out to the engine or engines through the pipes 99, as one or more engines can be operated by the same carbureter.

A series of inlet pipes 10-10 are placed around the carburetor casing 1 for the entrance of air, each pipe having a damper 11 for the control of the air admitted to the casing 1. Such oil as is not vaporized falls to the bottom of the casing 1 and can be carried off through the pipe 12.

Having thus described the nature and objects of my invention, what I claim as new and desire to secure by Letter Patent, is-

A carbureter having an exterior casing, a substantially large tubular heater or vaporizer completely inclosed within said casing, an inlet pipe connected to said exterior casing and to the vaporizer to admit exhaust gases from an engine to the vaporizer, said vaporizer having its periphery smooth and extending from the bottom of the exterior casing to within a relatively short distance of the top thereof and connected to a tubular neck, said neck extending from the top of the vaporizer to and beyond the exterior casing and comprising an outlet for said exhaust gases, in combination with a collar on said neck, a feed pipe project- Ciring Within the exterior casing and disposed Outside of the exterior casing in parallel over said collar to admit liquid to be vaporrelationship thereto foradmission of air ized by its distribution over said collar. into the casing, and means for Controlling 10 neck and vaporizer by the heat of said exthe air.

haust ases, means on the upper end of the n tes mony whereof I have signed my exterior casing for carrying of]? the vapor me 6 this'sp fi at n- 7 formed, and annularly disposed pipes on the SANDERS WALKER.
